The invention relates to vehicles, in particular to handcarts for transporting various goods under the most diverse conditions in which the owner of the goods may be

Known manual universal trolley containing running wheels and mounted on a frame with sides along its e perimeter and with a rotary handle in a longitudinal vertical plane,

In the invention, the lateral sides at the points of attachment to the carriage frame are rounded, the handle is mounted with the possibility of its fixation in the required positions, made U-shaped and its ends, hingedly connected to the frame, have bends whose radii are equal to the radii of curvature of the sides, the wheels are removable with half shafts for installing the latter in clamps fixed on the side sides of the trolley, also equipped with handles located in the planes of these sides, and on the front side of the trolley, opposite to the placement of the hands On the wheels, running rollers are installed.

On Fig, 1 shows a hand truck with a container, General view; figure 2 is a view along arrow a in figure 1; in Fig. 3-- a hand truck with a container when transporting it on rollers; figure 4 is the same, without a container, figure 5 is a view along arrow B in figure 4,

 The handcart contains a frame 1 of tubes with rectangular sides 2 and 3, to which a leash 5 is mounted on the axles 4, having position locks 6 that are fixed with pins 7 in the holes of the frame of the leash in the transport position (Fig. 1) or a retracted leash (figure 5). On the large sides of the sides there is a handle 8, which is installed flush on the tubes 9.

In the lower part of the frame, clamps 11 are attached to the brackets 10 of the rotating half shafts 12 of the big wheels 13 of the carriage.

The axles were clamped by a screw 14 with a wing-shaped head. On the disks of the wheels, rubber tires 15 are placed and holes 16 are made. On the small side of the side against the leash, kerchiefs 17 are fixed, in which rollers 18 are mounted on the axles. A rigid container 19c with a lid 20 or another container can be placed in the carriage between the sides. . It is made, for example, of a dust and water tight fabric covering a lightweight frame. Removable partitions may be placed inside such a container.

The manual universal trolley is operated in three main versions: as a trolley on large wheels using a leash; like a roller skating cart

in the presence of a rigid container with a lid (without using a leash); how simple is manual cargo with manual transportation, i.e. together of the container and the cart itself with the leash removed.

Consider the work of the cart in each option separately.

To work in the first embodiment, the truck was arranged as follows. Wheels 13 with rubber tires 15, half shafts 12 are inserted into the holes of the clamp 11 and fixed with a thumb screw 14c in this position, i.e. tighten the clamp, and due to this, the axles are rigidly fixed in the clamp 11. Then, the leash Bis is tilted by means of the clamps 6 and fix it about this inn. After that, the trolley is ready to work on the roads as with

hard surface, and on dirt roads, holiday villages. The cargo in this case can be oversized, placed directly in the truck body, formed by frame 1 and rectangular

5 sides 2 and 3. The cargo may be small or loose. In this case, a rigid container 19 with a lid 20 can be used, made, for example, from dust-tight containers or another

0 is similar to a container with or without a lid. If there is a variety of small cargo in the container 19, removable partitions can be installed.

In order to operate the trolley in the second embodiment 5, the following manipulations are carried out to prepare it for operation. The wheels 13 are removed from the trolley and folded by the axles 12 inside the wheels so that the axles fit into the holes 16 in the wheel disk.

0 and then moved to a fabric cover for transportation in a container 19 or separately. The container is installed in ku-. call of the cart and is filled with cargo: piece, loose, small-sized, etc.

5 Close and lock the lid 20 of the container. The container in the body is then secured with soft ties. After that, the trolley is placed on the roller rollers 18. The leash was fastened by the retainers 6 in the pressed against the frame 1

0 view (Fig. 4), A trolley with a load is ready for use on paved roads, in cramped conditions, i.e. at the landing sites of stations, airports and other similar conditions. At length-%

When using the trolley as such, the large wheels can be stored.

A trolley according to the third embodiment is used, mainly when loading cargo onto a vehicle platform when

it will need to be lifted from the floor, moved to a small distance and placed on a platform at a certain height from the floor. In this case, the trolley is connected to a container attached to it with a lid or other similar load. In this case, the load is manually transferred using the handle 9 to the desired location. The trolley may, if necessary, be varied.

MANUAL UNIVERSAL TROLLEY, comprising running wheels and a frame mounted on them with flanges along its perimeter and with a handle rotatable in the longitudinal vertical plane, characterized in that the side flanges are rounded at the points of attachment to the frame of the trolley, the handle is mounted with the possibility of fixation in the required positions, made U-shaped and its

puppy for the structural elements of the trolley from the side of the leash 5

A trolley with a container when stationary on the vehicle’s platform or simply on the floor or on the road can be on rollers 18 or on the surface of the side against handle 8. (56) French Patent No. 870380, cl. 63 V, 2.1942.

the ends pivotally connected to the frame have bends whose radii are equal to the radii of curvature of the sides, while the wheels 15 are removable with half shafts for mounting the latter in clamps fixed to the side sides of the trolley, also equipped with handles located on the planes of these sides but on

n r

and end faces of the trolley, opposite to the position of the handle, running rollers are installed.
